Discussion

There is a wind known in parts of the country as the "chinook" and it is often cited for its dramatic warming and drying capabilities. It has also become known as a "snow-eating" wind as there have been cases where significant snow literally disappears overnight after the wind kicks in and temperatures jump dramatically. Typically, one hears of this wind in places like North and South Dakota where wind flow from the higher levels of the front range of the Rockies descends onto the lower levels of the Northern Plains causing significant warming and drying. The Mid-Atlantic experienced its own mini-version of the "chinook" wind last night as winds kicked up after dark, temperatures rose, and our snow cover virtually disappeared overnight. High pressure will now build into the region for today and tomorrow and temperatures will stay above normal, but will be slightly cooler on Wednesday. Low pressure will approach the area on Thursday bringing some rain with it, and it could be just cold enough for a wintry mix to get involved at the onset of the event late Wednesday night or early Thursday. That rain will continue into Friday morning and then it'll turn colder as the weekend progresses.
